The MAX77696AEWI+T is a system-in-package(SiP) solution that provides an integrated power, charging, monitoring, and protection functions for system designs requiring a PMIC and a battery protection device. This SiP integrates the logic power converter (MAX77696) and thermistor-controlled current-limiting NTC (MAX14574) in a small package, enabling space savings and greater efficiency. This SiP is optimized for space-constrained applications such as wearable’s, portable electronic devices, and other systems with a 3V-5V input range.

The MAX77696AEWI+T\'s built-in diagnostics helps to improve efficiency and design reliability by providing real-time monitoring of power system operation. With the system-in-package solution, designers have the flexibility to configure the power system to their own design specifications by adjusting the settings with the integrated configurator. The integrated thermistor current-limiting NTC features fast response and precise protection threshold accuracy, which greatly improve the system accuracy and safety. The device is rated for a wide temperature range from -40 to +125°C and can survive exposure to overvoltage and transients, providing superior protection against unexpected power-supply and battery events.

The MAX77696AEWI+T architecture includes two independent domains, one for power management and one for protection. The power management side offers a highly integrated solution, spanning from battery input up to the system output stages, including four DC-DC voltage regulators, two LDO regulators, and a low-quiescent current buck-boost regulator. The protection side includes a configurable array of features, such as short-circuit protection and overvoltage protection for both the system and battery inputs.

The MAX77696AEWI+T provides safe and reliable operation in many types of applications, including wearables, low-voltage consumer electronics, and portable medical equipment. Its configurable current-limit feature, comprehensive protection mechanism, and wide operating temperature range make it an ideal choice for reliable system power design. The SiP solution enables a more efficient design by reducing layout complexity and component count, while also reducing system BOM costs.

In summary, the MAX77696AEWI+T is an ideal solution for a variety of applications, designed to provide reliable and cost-effective system power management and protection. Its integrated architecture and full configurability allows designers to customize the power system for their specific needs. This SiP offers superior protection in challenging systems with a wide temperature range, and provides real-time monitoring of system power operation.
